I have tried stronger low-bass increase as well, but it was clearly too much to my ears.
Yep depends also how much of a basshead and specific electronica listener one is. Though I listen everything non-bassy music through the same curve too.. if there's nothing in the music down below, there's nothing to affect.. but some stuff you don't even realize has it and it makes a great surprise what you are missing.
But still, the target of the curve is targeting a flat speaker response. Headphones simply need volume to feel down to 20hz. And HD800 actually handles it like a champ, unlike certain wimpy planars that start crackling under pressure..
